Fragrance oils are concentrated blends of aromatic materials, and like any fine ingredient they change when they are treated badly. Citrus notes are usually the first to suffer: they oxidise, lose their sparkle and can turn slightly sour. Well-stored oils, on the other hand, stay remarkably stable. Here is how professionals look after their stock.
The three enemies: heat, light and air
Heat speeds up every chemical reaction in the bottle. Store oils in a cool room, ideally between 15°C and 25°C, away from kitchens, generators and sunny windows. In Indian summers this matters: a warehouse shelf under a tin roof can easily exceed 40°C.
Light, especially sunlight, breaks down delicate molecules. Keep oils in their original lacquered or amber containers and in closed cupboards.
Air causes oxidation. Every time a large can is opened, fresh oxygen enters the headspace. As the level drops, the proportion of air grows.
Decant as you go
If you buy 5 kg but use 250 g a week, decant into smaller, full containers rather than repeatedly opening the master can. Fill each smaller bottle close to the top, cap tightly and label it with the product name and date.
How long do fragrance oils last?
There is no single number. Oils rich in citrus and aldehydes are more fragile; woody, musky, amber and oud profiles are usually very stable. As a working rule, use oils within about 12 months of opening and always follow the supplier's guidance for a specific batch.
Signs an oil has aged
- The top notes smell flat or slightly sharp compared with a fresh sample.
- Colour has darkened noticeably (some darkening is normal for vanilla-rich oils).
- Cloudiness or separation that does not clear at room temperature.
If in doubt, compare against a retained reference sample. Many of our trade customers keep a small sealed vial from every batch for exactly this reason.
